Approximately one week after her pregnancy ended in heartbreak with a miscarriage, singer Lily Allen was rushed to a hospital in an ambulance Friday night, requiring emergency treatment for septicaemia (blood poisoning), according to WENN news outlet.

The London native, 25, was six months' pregnant when she suffered her second miscarriage last weekend.

The Grammy nominee was reportedly recovering at home this week, and on Friday, she thanked fans via Twitter for the outpouring of support (including tweets from Katy Perry and Justin Bieber), adding, "I'm still very sick but the messages are helping me to be stronger."

But hours after posting that message, she was hospitalized. A statement issued by her rep indicates that she is responding well to treatment: "Her condition continues to improve."
